 ===== Objective: =====
-The zero gain amplifier (Q<sub>1</sub>, R<sub>2</sub>) and stabilized current source (Q<sub>2</sub>, R<sub>3</sub>) from activities 7 and 8 can be used in conjunction with a PNP current mirror stage (Q<sub>3</sub>,Q<sub>4</sub>) in negative feedback to build a circuit which provides a constant or regulated output voltage over a range of input voltages.
